II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 8,792,677 - Large Venue Security Method

Issued July 29, 2014

The Invention Explained

• Problem Addressed: The patent identifies the problem of fan violence at large sporting events and notes that conventional security measures are primarily reactive, responding to incidents only after they occur (’677 Patent, col. 1:11-54). It also notes the post-9/11 need to consider and prevent potential terror attacks at crowded venues (’677 Patent, col. 1:55-col. 2:3).
• The Patented Solution: The invention proposes a proactive security method that integrates multiple data streams. The system captures facial images and vehicle license plates of individuals seeking to enter a venue and compares this information against pre-compiled databases of persons with violent histories or other security concerns (’677 Patent, Abstract). Upon detecting a match, the system alerts law enforcement or security personnel, enabling them to investigate or deny entry before an incident can occur, as illustrated in the process flowchart of Figure 8 (’677 Patent, col. 2:40-67).
• Technical Importance: The method represented a shift from relying on passive observation and after-the-fact response to a data-driven, proactive approach for pre-screening attendees at large gatherings (’677 Patent, col. 2:7-14).

Key Claims at a Glance

• The complaint asserts claims 1-20 (Compl. ¶8). Independent claim 1 recites:
  • A method for reducing violent acts at a crowded venue, comprising providing entry ports for people and vehicles.
  • Forming a photographic image of each person approaching an entry port.
  • Comparing the photographic image to a first database of facial images of "persons who are known to be violent" to detect a match.
  • Alerting law enforcement upon detection of a match.
  • Using a license plate reader at a vehicle entry port to read license plates.
  • Comparing the license plate to a second database of vehicles associated with persons known to be violent to detect a match.
  • Alerting law enforcement upon detection of a match.
• The complaint reserves the right to assert other claims, including dependent claims.

U.S. Patent No. 10,248,849 - Technique for Providing Security to an Area

Issued April 2, 2019

The Invention Explained

• Problem Addressed: The patent addresses the shortcomings of conventional security, which relies on "outdated, reactive tactics" and the inability of human operators to proactively identify individuals with violent tendencies from video feeds alone (’849 Patent, col. 1:51-62; col. 2:1-5).
• The Patented Solution: The patented technique involves providing a "secure area" with at least one entry port where a camera captures a photographic image of each person seeking entry (’849 Patent, Claim 1). A computer compares this image to a database of "persons of interest." A key aspect of the claimed invention is its distributed architecture, where the secure area (e.g., a stadium) is controlled by a first party, but the database of persons of interest is controlled by a separate, second party, such as a "fusion center" (’849 Patent, Claim 1; col. 13:27-34). If a match is found, an alert is sent to security personnel at the venue.
• Technical Importance: This technology describes a security framework where venue operators can leverage external, specialized threat intelligence databases without directly controlling or maintaining that sensitive data themselves, enabling a more modular and potentially more powerful security screening process (’849 Patent, col. 2:54-67).

Key Claims at a Glance

• The complaint asserts claims 1-23 (Compl. ¶16). Independent claim 1 recites:
  • A method for providing security to an area, comprising providing at least one entry port into a "secure area."
  • Capturing a photographic image of each person approaching the entry port.
  • Comparing the image to a database of facial images of "persons of interest" to detect a likely match.
  • Alerting law enforcement or security personnel of a detected match.
  • A notable limitation requires that the "secure area is controlled by a first party and the database is controlled by a second party."
• The complaint reserves the right to assert other claims, including dependent claims.

III. The Accused Instrumentality

Product Identification

The complaint does not identify any specific accused products by name. It broadly refers to "devices/products, methods, systems, and processor-readable media" that Defendant "maintains, operates, and administers" (Compl. ¶8, ¶16).

Functionality and Market Context

• The complaint alleges that the accused instrumentalities provide functionality for "comparing captured license plate images to a database of license plate data for persons of interest" and "comparing captured facial images to a database of facial data for persons of interest for reducing violence" (Compl. ¶7, ¶9).
• It is alleged that Defendant provides these instrumentalities to customers to perform these security and alerting functions (Compl. ¶11, ¶19). The complaint does not provide further technical details regarding the operation of the accused systems or their market context, instead referencing preliminary infringement charts in Exhibits B and D, which were not filed with the complaint (Compl. ¶10, ¶18).

IV. Analysis of Infringement Allegations

No probative visual evidence provided in complaint.

The complaint alleges infringement but does not contain claim charts or detailed factual allegations mapping specific features of an accused product to the patent claims. It references Exhibits B and D for this purpose, which are not included in the provided document (Compl. ¶10, ¶18). The narrative infringement theory is summarized below.

• '677 Patent Infringement Allegations: The complaint asserts that Defendant's systems, methods, and products infringe claims 1-20 of the '677 Patent (Compl. ¶8). The infringement theory is that Defendant provides instrumentalities that perform the patented method of comparing both captured license plate images and facial images against databases of persons of interest and subsequently alerting security personnel (Compl. ¶7, ¶9).
• '849 Patent Infringement Allegations: The complaint asserts that Defendant's systems, methods, and products infringe claims 1-23 of the '849 Patent (Compl. ¶16). The infringement theory is that Defendant provides instrumentalities that perform the patented method of comparing captured facial images against a database of persons of interest to proactively identify threats at large venues (Compl. ¶15, ¶17).
• Identified Points of Contention:
  • Scope Questions: A central question for the '849 Patent will be whether the accused systems meet the "first party/second party" control limitation of claim 1. The analysis may focus on whether Axxon's customers (the "first party") "control" the database, even if Axxon or another entity (the "second party") populates it, potentially creating a mismatch with the claimed distributed architecture.
  • Technical Questions: The primary technical dispute will likely be evidentiary. Questions will arise as to whether the accused systems use databases that meet the specific claim definitions, such as a database of "persons who are known to be violent" ('677 Patent, Claim 1) versus a more generic watchlist. The specific functionality of the "alerting" step will also be a point of factual inquiry for the court.

V. Key Claim Terms for Construction

Term 1: "persons who are known to be violent" ('677 Patent, Claim 1)

• Context and Importance: This term defines the required contents of the databases for both facial and license plate comparison. The outcome of the infringement analysis may depend on whether this is construed narrowly (e.g., only those with convictions for violent acts at venues) or broadly (e.g., anyone on a security watchlist).
• Intrinsic Evidence for a Broader Interpretation: The claims themselves do not further limit the source of knowledge or type of violence. A party could argue this term covers any person known to any entity (including the system operator) to have any violent history.
• Intrinsic Evidence for a Narrower Interpretation: The patent’s background section focuses heavily on the specific problem of "fan violence" at sporting events, suggesting the term could be limited to individuals with a history of violence in that specific context (’677 Patent, col. 1:11-45).

Term 2: "database is controlled by a second party" ('849 Patent, Claim 1)

• Context and Importance: This limitation is central to the architecture of the claimed invention. Practitioners may focus on this term because infringement will hinge on whether Axxon's system, as deployed, satisfies this distributed control requirement or if it operates as a self-contained system controlled by the end-user.
• Intrinsic Evidence for a Broader Interpretation: The specification’s discussion of "fusion centers" as remote data hubs supports a distributed model where control is separate from the venue operator (’849 Patent, col. 13:27-34). "Control" could be interpreted to mean management or populating the database, not necessarily ownership or hosting.
• Intrinsic Evidence for a Narrower Interpretation: The claims repeatedly specify that the database is "remotely located from the secure area" ('849 Patent, Claim 15), which may support an interpretation requiring physical and operational separation. If a customer hosts the database on its own servers, it might be argued that the customer, not a "second party," ultimately "controls" it.

VI. Other Allegations

Indirect Infringement

The complaint alleges both induced and contributory infringement. It asserts that Defendant "actively encouraged or instructed" its customers on how to use its products in an infringing manner and that the accused components lack substantial non-infringing uses (Compl. ¶11-12, ¶19-20). These allegations are not supported by specific factual examples, such as citations to user manuals or marketing materials.

Willful Infringement

The complaint makes a conditional allegation of willfulness, stating that if discovery reveals Defendant had pre-suit knowledge of the patents, its infringement should be declared willful, justifying enhanced damages (Compl. ¶VI.e).

VII. Analyst’s Conclusion: Key Questions for the Case

This litigation will likely center on the following key questions for the court:

• A central issue will be one of evidentiary sufficiency: Given the complaint’s reliance on un-provided exhibits, what specific evidence can Kephart introduce to prove that Axxon’s products actually perform every step of the claimed methods, particularly concerning the precise content and control of the databases used?
• A key legal question will be one of architectural scope: Can the '849 Patent’s requirement that the "database is controlled by a second party" be met by Axxon's commercial products, or does the typical customer-hosted software model fall outside the scope of the claimed distributed-control architecture?
• A third core issue will be one of definitional scope: Can the term "persons who are known to be violent," central to the '677 Patent, be construed broadly to cover general-purpose security watchlists, or will it be narrowed by the patent's specific focus on the problem of "fan violence"?
